To all whom it may concern:

Be it known that we, OSCAR RHODES SMITH and EDGAR ARMITAGE SMITH, citi-' zens of the United States, residing at lVind- $01, in thecounty of Bertie and State of North Carolina, have invented certain new and useful Improvements in Brake-Operating' Attachments for Automobiles; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

()ur invention relates broadly to improvements in brake mechanisms for automobiles and more particularly to an attachment to connect the service brake pedal of a Ford automobile with the clutch operating arm of the usual transverse controller shaft which is operated by a hand lever and acts also to apply the emergency brakes located in the drums of the rear wheels. Experience has taught that the emergency brake drums often become so tilled with grease from the rear axle casing as to prevent the emergency brakes from operating. On account of this it isthe polic' ot' a number of driversto totally disconnect the emergency brakes "from the controller shaft, using only the service brake.

By this arrangement. however. there is no way of applyingbrakes to the car when the same is standing and thus when the engine is started, the vibration often causes the en tire machine to start prematurely. To over comethis diiliculty. we have devised the present invention by whose use the service brake will be applied when the hand lever ofthe controller shaft is drawn rearwardly to throw the clutch out.

\Vith the foregoing end in view, the invent on. resides in the unique features of con strii'cfi'on and combination of parts herein-' on the 3,;

Fi 5 is an edge elevation of the vertical bar which is secured to the service'brake foot pedal.

In the drawings ahove briefly o ribcd, l. designates the transmission now 0; a

Ford automobile, C the clutch pedal, R the reverse pedal, and B the service brake pedal. The clutch lever C is connected by the usual link L with the rocker arm A of the clutch controlling shat't. S, arm cooperating with the cam C on the upstanding crank arni'A ot' the transverse control shaft C S. The shaft C is provided with. depending crank arms A usually connected with the brake rods R which lead to the emergency brakes within the drums of the rear wheels, and said shaft is equipped with the hand lever ll L by llltlIlS of which it may be rocked. The operation of the parts so far described is well known, the hand. lever H L serving through the medium of the parts A, l. A and h to throw the clutch out and to also a ppl y the emergency brakes when said hand lever l'l I1 is pulled rearwardly. above stated. however, the rods R are often detached so that the emergency bra-kesare not applied, but due to the nature of the present invention, the service brak pedal B automatically depressed when the lever Ii L is pulled rairwardly.

The invention consists 'brieti of a rigid y bar 1 secured by a clamp .3 to the lower end of the pedal it and extending below the pivot of said pedal. and a link pivotally connected by means of a clamp 4 with the arm A. said link having a sliding connection with the lower end oi the bar 1.

The upper end oi the bar 1 e ends obliquely for contact with the similarly extending lower end of the pedal B, so as to dispose the body of said bar vertically. the lower end oi said body-being gircn a quarter turn at 5 and formed with an eye 5 through which the link lr-passes sliciably, said link having any suitable stop in front of said eye. said stop preferably consisting of a pair of nuts (3 and 7, the one l cking the other. The, clamp 4 is preferably formed of a single metal bar bent into the forni of an 8,

one loop of'the '5 receiving the arm A" while the link 3 extends into the other loop, bolts 8 and i) being provided respectively For contracting the first named loop around the arm A and for pivotally connecting the link with the other loop.
